Looks good. Wanted to apply. But this requires your previous patch, so
please rebase on a new version of that! Thanks!
TCP Fast Open (TFO) speeds up the opening of successive
TCP)connections between two endpoints.It works by using a TFO cookie
in the initial SYN packet to authenticate a previously connected client.
It starts sending data to the client before the receipt
of the final ACK packet of the three way handshake is received, skipping
a round trip and lowering the latency in the start of transmission of
data.
